APPLICATIONS

10. Calculation and selection of equipment of local exhaust ventilation systems of galvanic workshop

10.1. Filter Matching

To clean contaminated air before its release into the atmosphere, filters are provided in exhaust ventilation systems. The grade and type of filters according to the regulatory documentation shall correspond to the nominal flow rate of the system and the type of neutralized damage.

The combination of local suction from various baths is carried out according to the types of emerging pests.

The accepted filters have the following aerodynamic characteristics as shown in Annex Table 8.

10.2. Aerodynamic calculation

Aerodynamic calculation of air ducts is carried out to determine the dimensions of their cross section, as well as pressure losses in individual sections and the system as a whole.

The calculation is summarized in Table 9 of the annex.

For calculation diagrams of systems, refer to Appendix.

11. Calculation and selection of common exchange equipment

exhaust systems

11.1. Aerodynamic calculation of common exhaust systems

Aerodynamic calculation of common-exchange ventilation systems of rooms of galvanic and woodworking shops is carried out in the same way as aerodynamic calculation of plenum ventilation systems.

The calculation is summarized in the annex table 10.

For calculation diagrams of systems, refer to Appendix.

11.2. Calculation and selection of equipment

Woodworking shop

For systems B1 and B2 having a capacity, we accept the roof fan VRK 90/636D.

Technical specifications of fans are given in the appendix.

Galvanic workshop

Since the multiplicity of air exchange is higher than the five-fold air exchange in the workshop - air removal from the upper zone is not required. General-exchange exhaust ventilation systems in the galvanic workshop are not designed.
